When men turn into flies, it's because science. When women turn into wasps, it's because vanity.

Believe it or not, this movie where a woman turns into a wasp after using an experimental wasp jelly-based beauty product isn't very good. The plot wasn't great, the acting wasn't great, the tension was non-existent. Here's a screenshot to answer your only outstanding question.

I wish this had been a woman-insect movie where the woman had some level of agency [finger curls down on monkey's paw].
